But you did ask in a branch of a thread about a Qt3D change, so I 
answered with respect to the part that I have knowledge about.

I was asking because I'm genuinely curious about the answer. I myself am 
using a Mac from 2011 that happily runs 10.10. I was not inferring that 
everybody should upgrade, but wondering how much of a need still remains 
to drive support for older flavours.

As a director of a company that sells support I have to justify 
investments into supporting said older releases, so if there is no 
requirement or demand for it then we won't consider it. As it stands 
Qt3D has a minimum requirement of OpenGL 2 or OpenGL ES 2 but we don't 
have support for anything older than OS X 10.8 in the CI so support for 
say 10.7 can only be on a best efforts basis. Of course if somebody 
wants to pay for such support, then we would be happy to investigate this.

Looking at the CI for qtbase for e.g. shows a similar story for OS X 
versions but I can't say what the official support is there.

Kind regards,

Sean
